MHD115A-058-NP1-BA
MHD Synchronous Motors
The Bosch Rexroth Indramat MHD115A-058-NP1-BA from the MHD Synchronous Motors series is a high-precision Servo Motor engineered for demanding automation tasks. This Product Type features a Motor Size 115 frame with a compact Motor Length A, complemented by a flange size of 192 mm and a centering diameter of 180 mm for seamless mounting. The robust winding code 058 delivers consistent current-to-torque conversion, ensuring reliable operation in closed-loop applications. Designed with a keyed shaft and integrated shaft seal, it guarantees secure power transmission and environmental protection.
Featuring a built-in holding brake with a holding brake torque of 70.0 Nm, this model maintains position integrity during power-off conditions. At standstill, the motor delivers a continuous torque of 32.0 Nm, making it ideal for vertical axis support or safety-critical holds. Position feedback is provided by a digital servo feedback (HSF) encoder and uses a relative type of position detection for precise motion control.
Thermal management relies on natural convection housing cooling, eliminating the need for auxiliary fans and reducing maintenance points. Power is routed via an output connector directed to side B, simplifying cable routing in compact cabinets. This versatile, high-torque servo solution from Bosch Rexroth Indramat is designed for seamless integration into advanced machine tools, robotics, and packaging systems where reliability and precision are paramount.

Frequently Asked Questions
Why is digital servo feedback important for motion accuracy?
The feedback device measures rotor position in real time. The continuous monitoring allows precise synchronization between command and motion output.
How does the relative position feedback affect system startup calibration?
The motor must reference a home position at startup for accurate alignment. The calibration ensures consistent positioning with the external control system.
How does winding code selection influence current efficiency?
The winding configuration defines the motor’s electrical to mechanical conversion ratio. The optimized design improves torque consistency and reduces heat buildup.
Why is shaft sealing crucial in industrial environments?
The seal keeps dust and liquid away from internal bearings. The protection extends motor life and maintains reliability under harsh working conditions.
How does side B power connection assist in cabinet layout design?
The connector position allows direct cable routing along the mounting plane. The arrangement simplifies wiring and improves accessibility during maintenance.
